If you click the "Search" link in the header of each forum, type "invalid compiler [YOUR ANSWER IS ALREADY THERE. SEARCH THE FORUMS!]" and hit "Search" you get six pages with answers, partly answers that help directly, partly answers like mine.
If you are to lazy to do so, and if you ignore what I wrote about that, you are wrong here (that's my opinion).
All moderators, devs and administrators do the work in their sparetime.
We all have a real live, have families, have to earn money ...
But as I wrote, due to legal issues we have to read each and every post.
And it's annoying to answer the same question over and over again, even not answering but just reading needs time.
The purpose of the forums search is to avoid such unnecessary noise.
